Abstract

This paper attempts to examine the impact of rising fossil fuel prices on the increasing impact on the demand of alternative fuels (biofuels), and its impact on food availability in Indonesia. An econometric model using simultaneous equations is employed. An increase in world crude oil price for 0,192 percent caused the price of real Indonesian palm oil export raised by 10,64 percent. Consequently, a larger biodiesel production is needed to meet their crease of world´s consumer demand for biodiesel. Also, with the increase in real export price of Indonesian palm oil, it will encourage palm oil producers to push their export volume. Indonesian palm oil exporter expected to increase by 6,37 percent to finally push the domestic CPO price increase for 1,85 percent. Rising domestic oil prices are causing oil demand in the palm oil industry to decline by 0,49 percent and in the end resulting in the decline of palm oil production by 1,56 percent.

Abstract

ABSTRACTIndonesia is the biggest palm oil producer and exporter in the world. In2008, Indonesia contributed 34.3% of total palm oil world production and 84.6%of production was exported as crude palm oil (CPO).In the world’s market, the growth of palm oil consumption and importwere 9.66%/year and .34%/year. In supply side, palm oil production and exportincreased 7.94%/year and 9.55%/year respectively. It reflected global excessdemand which influence palm oil price in world market, 1.69%/year. Demand forIndonesian CPO also to fulfill the raw material for energy. This situation willinfluence several aspects in Indonesian palm oil industry, in order to ensure theavailability of palm oil to fulfill national necessity for cooking oil industry and biodiesel industry.By using annual data 1979-2008 periods, an econometric approach wasapplied in this study. The goal of this study is to analyze (a) the analyze thecorrelation between world petroleum oil price with CPO world price, (b) theanalyze the effect of petroleum oil price toward domestic palm oil demand, (c) tosimulate the effect of petroleum oil price for 18,71% toward several aspects inIndonesian palm oil industryThe findings of the study show that (a) since 2000 there was the strongcorrelation between world petroleum oil price with CPO world price, that reflectthat CPO is used for raw material of bio diesel industry; (b) petroleum oil pricepositively influenced domestic palm oil demand, and (c) the rise of worldpetroleum oil price will affect the domestic cooking oil industry, i.e. the cookingoil supply will decrease, and the cooking oil price will increase due to the lack ofCP O for cooking oil industry, while the bio diesel industry was start to grow.Key words: crude palm oil, petroleum oil price, cooking oil, bio diesel

Abstract

The purpose of this study is to analyze the company’s internal and macroeconomic conditions on the ratio of dividend distribution, as well as knowing the conditions of coal companies on the IDX during the decline in coal prices. The weakening of the global economy has resulted in a decline in various commodity prices, including coal prices. Various studies were conducted to determine the factors that influence the poor condition of sectoral mining indices in these weakening conditions a few years ago. The coal subsector has the largest capitalization in the mining sector. Multiple regression models are used to analyze 55 samples from 11 coal subsector companies. The research period was carried out from 2013 to 2017. The results showed that return on assets, exchange rates, world oil prices had a positive and significant partial effect on the dividend payout ratio of the coal subsector. The implications of the findings are management of coal subsector company needs to pay attention to internal and external factors so that they can distribute dividends regularly.

Abstract

West Java province's junior secondary school enrollment rate is still below the Millenium Development Goal of universal primary education by 2015. Panel data of 26 districts in West Java, Indonesia, was used to analyze the determinant factors of junior secondary school enrollment rate. The study shows that GRDP per capita and education level of the household head positively infuence junior secondary enrollment rate, in contrast poverty rate and number of child labour had negative impact. This study suggests that government should increase local revenue to enable the people to have sufficient income for attending school, especially for the poor. The government is also expected to increase the availability of schools.AbstrakCapaian Angka Partisipasi Sekolah (APS) SMP Provinsi Jawa Barat yang masih rendah menunjukkan belum tercapainya tujuan MDGs tahun 2015 tentang pendidikan dasar. Dengan menggunakan analisis regresi data panel 26 kabupaten/kota di Jawa Barat tahun 2007-2011, studi ini menemukan bahwa faktor yang menjadi determinan APS SMP adalah PDRB per kapita dan pendidikan orang tua. Adapun kemiskinan dan partisipasi kerja anak usia 13-15 tahun akan mengurangi partisipasi sekolah. Oleh karena itu, untuk meningkatkan partisipasi sekolah SMP, terutama anak dari keluarga miskin, selain peningkatan anggaran pendidikan untuk mendukung partisipasi sekolah (beasiswa dan ketersediaan/fasilitas sekolah), hal itu juga harus didukung dengan penurunan tingkat kemiskinan. Selain itu, peningkatan anggaran pendidikan lebih pro-masyarakat miskin dengan meningkatkan ketersediaan sekolah.

Abstract

Pangan merupakan salah satu kebutuhan dasar manusia yang paling asasi. Beras masih menjadi komoditi utama penopang ketahanan pangan nasional. Perum BULOG penyelenggara usaha logistik pangan pokok yang melakukan penyebaran persediaan melalui kegiatan angkutan antar Divisi Regional (Divre). Penelitian bertujuan merancang sistem angkutan antar Divre. Metode penelitian menggunakan metode perancangan sistem yaitu kegiatan merancang sistem melalui tahapan-tahapan tertentu untuk menjawab permasalahan yang ada. Menggunakan model optimasi dalam Pemrograman Linieryaitu Transportation Problem (Permasalahan Transportasi). Total biaya angkutan untuk tahun 2010 dengan model optimasi lebih rendah Rp. 17.461.590.772,- apabila dibandingkandengan total biaya yang dihitung dengan metode yang digunakan saat ini. Penggunaan pemrograman linier untuk angkutan antar Divre Perum BULOG menghasilkan optimasijumlah persediaan yang diangkut, jalur dan biaya angkutan. Model optimasi tidak hanya dilakukan terhadap kondisi ideal tetapi juga terhadap kemungkinan adanya perubahan perubahan melalui analisa pasca optimasi. Hasil analisa menunjukkan bahwa sistem operasional angkutan terbagi kedalam Sistem Perencanaan, Sistem Pelaksanaan, Sistem Evaluasi dan Sistem Penunjang. Keempat sistem tersebut saling berkaitan satu dengan lainnya dengan tujuan akhir adalah pelaksanaan angkutan antar Divre. Sistem ini banyak ditunjang oleh penggunaan pemrograman linier untuk mendapatkan biaya angkutan yang minimum.Food is one of the most basic human rights. Rice is still a major commodity supporting the national food security. Perum BULOG is the business organizer who makes the distribution supplies through transport activities among the Regional Divisions (Divres). The research aims to design a transportation system among the Divres. Research method used for designing the system is a system design activities through certain stages to address existing problems using Linear Programming optimization model in the Transportation Problem. The total cost of transport for 2010 was Rp. 17.461.590.772 which is lower compared to the total cost calculated by the method used today. The use of linear programming to transportation among Divres produces transported amount of inventory optimization, route and transportation costs. Optimization model is not only carried out on ideal conditions but also to the possibility of changes through the postoptimization analysis. The result showed that the operational system of transportation is divided into Planning System, Support System, Evaluation System and Integrated System. The four systems are interconnected with each other with the ultimate goal is the implementation of transport among Divres. This system is much supported by the use of linear programming to obtain the minimum transportation cost.
